Abstract

We report a wavelength-tunable multi-point pump scheme of the semiconductor disk lasers (SDLs). By designing an external cavity of SDL with an intra-cavity transmission grating, multiple pump gain regions share the same resonator. The effect of the intra-cavity grating on the output laser power, wavelength, and beam quality was investigated. The emission wavelength could be tuned over a bandwidth of ∼ 18 nm. With multi-point pumping, we achieve the laser output power with almost no loss, and further improvement is limited by the thermal effect. The changes in the beam are due to the mode selectivity by the intra-cavity grating. DOI:

基于腔内传输光栅的波长可调谐多点泵浦半导体圆盘激光器

本文报道了一种波长可调的半导体圆盘激光器多点泵浦方案。通过设计带有腔内传输光栅的SDL外腔，多个泵浦增益区域共享同一个谐振腔。研究了腔内光栅对输出激光功率、波长和光束质量的影响。发射波长可以在~ 18 nm的带宽上调谐。通过多点抽运，我们实现了几乎没有损耗的激光输出功率，进一步的提高受到热效应的限制。光束的变化是由于腔内光栅的模式选择性。DOI:

期刊介绍： Chinese Optics Letters (COL) is an international journal aimed at the rapid dissemination of latest, important discoveries and inventions in all branches of optical science and technology. It is considered to be one of the most important journals in optics in China. It is collected by The Optical Society (OSA) Publishing Digital Library and also indexed by Science Citation Index (SCI), Engineering Index (EI), etc. COL is distinguished by its short review period (~30 days) and publication period (~100 days). With its debut in January 2003, COL is published monthly by Chinese Laser Press, and distributed by OSA outside of Chinese Mainland.
